PETROLEUM-BURN ER.

SPECIFICATION forming part of Letters Patent No, 443,808, dated December30, 1890. Application filed December 16, 1889- Serial No. 334,001. (Nomodel.)

T0 to whom, it may concern.-

Be it known that I, DANIEL C. \VILGUS, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a certain new and useful Improvement inPetroleum- Burners for Furnaces, of which the following is a full,clear, and exact description, reference being had to the accompanyingdrawings, forming part of this specification.

Figure 1 represents a side elevation of my improved petroleum-burnerarranged as when applied in the furnace of alocomotive-boiler. Thisfigure will be fully understood by those skilled in the art, and isshown to illustrate the manner of connecting the steam and oil pipes.Fig. 2 represents a central vertical section of such burner with theinductionconduits broken away. Fig. 3 is an end view of the burner shownin Fig. 1. Fig. 4 is a transverse section taken at line pg of Fig. 2,and Fig. 5 is a transverse section taken at line w on.

My improved petroleum-burner is adapted for use with either horizontal,vertical, locomotive, or Hazleton steam-boilers.

A primary object of my burner is to reduce the oil or petroleum to agaseous condition; also, to prevent the oil from being mixed with thesteam while being forced through their conduits.

My invention comprises the combination of the outer steam-pipe A, havingthe forwardly-projecting lip L, the longitudinallyperforated internalcollar .8 near the end, and the annular chamber D in front of suchcollar, the internal oil-pipe O, forced or screwed into the rear end ofsuch collar, and the radiallyperforated burner or oil tip or shield E,provided with the tubular stem F, which is inserted into the front endof the collar B and secured by the set-screw S, which allows of theadjustment and removal of the burnertip structed for various conditionsof use. In the form shown in Figs. 1, 2, 4:, and 5 the burner isdesigned to throw an upwardlyprojected flame and also a forwardly=projected flame. For this purpose I have provided three end perforations G,opening from The burner-tip may be variously 0011-,

the tubular stem of the burner-tip which connects with the oil-pipe O,and beneath these end perforations I provide a transverse slot orpassage H, which communicates with the annular chamber D in frontofcollar B, and

.into which chamber the longitudinal perforations J through the collaropen from steampipe A. This slot is formed by so constructing andarranging the burner-tip with relation to the lip as to leave a spacebetween the lower side of the tip and the upper face of the lip L, whichprojects forward from the lower side of the front end of the steam-pipe.The steam escapes from the steam-pipe through perforations J intoannular chamber D, and thence laterally through a space M left betweenthe burner-tip and the end of the steampipe above the lip, thusproducing a radial jet of steam just to the rear of the radial holes ofthe burner-tip. The oil is subjected to sufficient pressure to cause aflow of oil from the radial perforations K. The oil is not subjected toa blast from the steam, but is carried outward from the burner byfrictional contact and is mingled with the steam and consumes in a clearand effective flame, the

effects of which are not injurious to the boiler or furnace. hen theburner is designed for use under horizontal boilers, the end holes G andslot II are employed, and the oil flows from the holes G as well as fromthe radial holes K, and is caught by the horizontal sheet of steam whichissues from slot H and is carried along under the boiler, where it isconsumed.

It will be understood that in practice the oil is introduced into theinternal oil-pipe through the oil-feed pipe 0', and that the steam isintroduced into the outer steam-pipe A through the steam-feed pipe A.

The valve V is designed to admit steam into feed oil pipe 0 whenever itis desired to cleanse it by blowing out the accretions which may collectfrom the oil.

The operation of my burner is essentially different from thoseheretofore made, in that the oil is delivered into the furnace immedi=ately in front of a fan-shaped or radiate jet of steam, which does notcome into contact with the oil until both have issued from the burner.The oil is not blown from the burner,

and therefore the flame is not so destructive to the furnace and burneras with other burners.

The gist. of my invention lies in the construction which produces thisoperation, and I desire to secure broadly, the combination, in anoil-burner, of a steam pipe, an oil-pipe within such steam-pipe, and theoil-tip con sisting of a shield E, extending across in front of themouth of the steam'pipe to form with the end of the steam-pipe a radiatesteamdischarg'e passage from the interior of the steam-pipe at rightangles to the axis of such pipe and provided with the oil-tube Icommunicating; with the oil-pipe, and also providedwith the oil-passagesK, communicating with the oil'tube and opening at the periphery of theshield in front of the radiate steam-passage M out of the path of thesteamdiseharge. It is obvious that this principle of construction can becarried out without providing a passage between the lip of thesteanrpipe and the lower side of the tip, and it is not absolutelessential for such construction that there be any such lip, and 1' donot desire to be limited to such construction.

Now having described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. An oil-burner comprising the con'ibination of a steam-pipe, anoil-pipe within such steam-pipe, and the oil-tip consisting of a shieldextending across in front of the mouth of the steanrpipe to form withthe end of the steam-pipe a radiate steam-discharge passage from theinterior of the-steam-pipe at right angles to the axis of such pipe andprovided with the oil-tube F, communicating with the oil-pipe, and alsoprovided with the oil-passages K, communicating with the oil-tnbe andopening at the periphery of the shield in front of the radiatesteam-passage M out of the path of the steam-discharge.

2. The combination ofthe outer steam-pipe having theforwardly-projeeting lip and the longitudinally-perforated internalcollar, the internal oil pipe, the radiallyperforated burner-tipprovided with the tubular stem and with the end holes and so arrangedwith relation to the lip as to leave a space between the lower side ofthe tip and the upperface of the lip.

53. The burner comprising the combination of the oil-pipe, thesteam-pipe having on its lowerside the lip projecting forward beyond theupper main face of the end of such pipe, and the radially-perforatedoiLti p arranged above such lip to form astcam-passage between the lipand the lower side of the tip.
